    logical mode, vector_allocation_domain will return all online cpus aka
    the 8 cpus.

    phys_flat mode, vector_allotcation_domain will only the cpumask with
    the cpu set..

    target_cpus is the cpus that could be possible to used to take vector
    and process that irq. so at least it should be online.
